The Crucial Role of Hydration in Pregnancy: Nurturing Both the Mom and the Baby

Pregnancy is a miraculous journey that brings about numerous changes in a person’s body. These changes, such as vomiting, hormonal changes, increased expiration, etc., contribute to increased water intake needed in the mother’s body.

One often overlooked but critical aspect of prenatal care is proper hydration. Staying well-hydrated during pregnancy is not just about quenching thirst; it plays a pivotal role in supporting the physiological changes that occur during pregnancy.

In this article, we will explore the myriad benefits of proper hydration and maintaining adequate water intake throughout pregnancy.

How much water is enough water

According to the American Congress of Obstetricians and Gynecologists, you should drink 8 to 12 cups (64 to 96 ounces) of water every day during pregnancy.

It is also important to note that while water is the best source of hydration, other fluids such as herbal teas and fruit juices can contribute to overall fluid intake. However, it is essential to monitor caffeine and sugar intake from these sources, as excessive amounts can have negative effects on pregnancy. Additionally, it goes without saying that alcohol consumption should NOT be considered at any point during pregnancy as a source of water intake or for any other reason.

Watch out for signs of dehydration

On the one hand, it is important to maintain proper hydration and prevent dehydration for a safe and smooth pregnancy. On the other hand, it is just as important to pay attention to the body for a proper response against thirst or dehydration, when the signs are present.

The most common signs of dehydration include:

  • a feeling of thirst
  • darker urine color, with a stronger smell
  • less frequent urination than usual
  • constipation
  • Fatigue
  • feeling dizzy, tired, or lightheaded
  • sunken eyes
  • dry mouth, lips, or tongue

If you feel like you may be at risk of dehydration or experiencing these symptoms, make sure you are consuming enough water and notify your healthcare provider at once.

Now we review some of the benefits of adequate hydration in pregnancy.

Fetal, and Amniotic fluid development

One of the most important roles of water intake during pregnancy is its ability to support the increased blood volume in the body. As pregnancy progresses, blood volume expands to support the growing needs of the fetus and placenta. Water is a fundamental building block for the cells that form the fetus. Adequate hydration supports the growth and development of the baby’s organs, tissues, and overall structure.

Water also plays a vital role in the formation of amniotic fluid. Amniotic fluid is vital for the baby’s buoyancy, protection, and lung development. Proper hydration helps maintain optimal levels of amniotic fluid, reducing the risk of complications such as oligohydramnios (low amniotic fluid levels), which may lead to issues with fetal development and increased risk during labor.

Alleviating common pregnancy-related symptoms

Hydration can help alleviate some common discomforts associated with pregnancy, such as swelling, bloating, headaches, constipation, hemorrhoids, and urinary tract infections (UTIs). Drinking enough water supports the body’s natural mechanisms for fluid balance and can contribute to overall maternal well-being.

Body temperature regulation

Proper hydration also supports the body’s ability to regulate body temperature. This is particularly important during pregnancy, as pregnant women are more susceptible to overheating, especially in warmer climates. This can further be exacerbated through dehydration. Proper hydration plays a key role in regulating body temperature, reducing the risk of conditions like heat exhaustion or heat stroke, which can be harmful to both the mother and the baby.

Pregnancy-related complications

In addition to supporting physiological changes, proper hydration can help prevent complications such as preterm labor and low amniotic fluid levels. Staying well-hydrated is crucial in preventing neural tube defects and other congenital abnormalities. Water aids in the transportation of essential nutrients to the developing fetus, ensuring proper closure of the neural tube, which eventually forms the baby’s brain and spinal cord.

Gestational Diabetes

Maintaining proper hydration can contribute to reducing the risk of gestational diabetes. Water assists in metabolizing glucose and supports the body’s natural insulin production, which is essential in preventing elevated blood sugar levels during pregnancy.


In conclusion, proper hydration is an often underestimated but critical component of prenatal care. It is essential for the optimal development of the baby, the prevention of birth defects, and the overall well-being of the expectant mother. As you embark on this incredible journey of pregnancy, remember to prioritize your water intake, ensuring a healthy, happy pregnancy for both you and your baby. Always consult with your healthcare provider to determine the appropriate amount of water intake based on your individual needs and circumstances
